It all fit together SNUG. The only othe viable option would have been a Battle Arms Development clamp on front sight post. I figured this at least gives me the option of running with or without a front sight.

The original Dissipator was a 16” barrel with a rifle length gas system and handguard. That didn’t work out too well, due to the short dwell time and weak gas, so they made a low profile gasblock at the carbine length and used a faux gasblock at the rifle length. This allowed the efficiency of a trusted Carbine gas system with rifle length sight radius.
